基于Web的变电站监控系统设计

出于电力企业变电站综合管理信息化的需求,建立一套基于Web服务器的变电站监控系统。该系统将变电站管理、改扩建管理、变电站信息表梳理等功能组件封装于Web服务器中,并利用SQL Server 2019数据库技术对系统数据进行存储与管理,形成一套基于MVC框架的变电设备在线管理方案,以变电站管控统计功能模块为例展示界面设计结果。

Supporting web services reuse by semantic service component and composition pattern

Due to the fact that the existing web service description methods cannot address the issue of service reuse of various levels of granularity, the concept of service component is introduced, which packages together web services and choreography, and their operations and properties are presented in a consistent and uniform manner. Service components are published externally as normal web services and can thus be employed by webbased applications. In order to improve reusability and testability of service components, the concept of composition pattern is also proposed, which presents the relationships among service components. The relationships and relationship compositions have a rigorous semantic, so that composite components can be validated at the configuration stage. The composition patterns support to integrate service components of various levels of granularity. Experience indicates that the application assembly can effectively be conducted by understanding, selecting, and reusing components easily.

基于SOA的油气资源评价系统设计与实现

传统的开发模式很难将多源、异构的地学数据集成起来。本文建立了以SOA为基本架构、分层的油气资源评价服务体系结构,使用Web服务对已有的数据访问组件和地学计算组件进行封装和发布,与新开发的地学Web服务组件一起由WSM统一注册和管理,使用BPEL进行灵活地流程设计满足不同评价的业务需要,通过门户等多种客户端工具调用评价服务并将结果展示给用户。应用结果表明,采用SOA实现了地学数据和应用一体化集成与共享,达到了油气资源评价系统要求,为地学系统开发提供了一个新的参考模型。

高校信息化平台遗留系统的重用设计与实现

目前,随着国家推进国民教育资源的优化组合,许多高校进行扩建和合并,增设了院系,新建或接收了新校区,信息系统规模不断扩大。新增院系和校区的信息系统与主校区的信息系统无法有效融合,大量需要共享的关键信息被封闭在相对独立的系统里。如何对现有遗留系统进行统一规划,封装成可重用的Web服务组件,从而集成各个孤立的信息系统,消除"信息孤岛"现象,实现遗留系统的重用设计,是高校信息一体化平台建设中的亟待解决的问题。
